Abstract

Process for improving the slip properties of a ski sole made of high density polyethylene with a molecular weight greater than 1x10<6>, consists, continuously: - in feeding a chamber with the said polyethylene in powder form; - in subjecting the said powder in the said chamber to an instantaneous compression; - in passing the certain polymer successively through a heated enclosure comprising a static mixer and then through a filtering grid; - in then extruding the polymer thus mixed and filtered through a hot die with calibrating lips; - in then cooling and calibrating the tape obtained by passing between two cooled plates; - and then drawing the cooled tape obtained using a haul-off line; - and finally, in receiving the treated tape in reel form. <IMAGE>
